VACCINE-=SHIELD.

SPECIFICATION forming part of Letters Patent No. 695,270, dated March11, 1902. Application filed December 6, 1901. Serial No. 84,763. (Nomodel.)

To (tZZ whom it may concern:

Be it known that I, GEORGE M. BERINGER, a citizen of the United States,and a resident of Camden, New Jersey, have invented certain Improvementsin Vaccine-Shields, of which the following is a specification.

The object of my invention is to provide a shield especially adapted forthe protection of wounds caused by vaccination, which will be light andsubstantial and which will be thoroughly ventilated, theventilating-openings being out of contact with any wearingapparel, so asto give free ventilation and prevent the abrasion of the garment incontact with the shield, which at present causes undue inflammation bythe lint accumulating on the surface of the wound.

My invention, which is especially designed as a vaccine-shield, can beused to protect other wounds or eruptions on the skin without departingfrom the invention.

In the accompanying drawings, Figure l is a perspective view of myimproved shield. Fig. 2 is a longitudinal sectional view. Fig. 3 isatransverse sectional view. Fig. 4 is a 1ongitudinal sectional viewshowing the washer of adhesive material by which the shield is attachedin position. Fig. 5 is a plan view of Fig. 4., and Figs. 6 and 7 areviews of modifications of my invention.

A is the body of the shield, which is preferably made of transparentcelluloid. a'is the dome of the shield, and ct is the base-flange, whichin the present instance extends entirely around the shield, but may beonly at each end in some cases. The inclined walls a extend from thebase-flange to the dome, as shown in Fig. 1.

I form corrugations b in the walls at intervals, as shown in Fig. 1,which stiffen the walls,so that the shield can be made of very lightmaterial and yetwill prevent the crown breaking down by any ordinarypressure.

These corrugations preferably do not eX-' tend into the surface a, sothat the surface is smooth, and I preferably round the corners at thejunction of the side walls and the crown, so that when a garment restsupon the shield, lint will not be rubbed from it.

In order to thoroughly ventilate the shield, I provide openings 0 withinthe corrugations, and I preferably form some of these openings near thebase of the shield, while others I form near the crown. Thus theopenings are protected entirely from the garment, and the sharp edgearound the openings cannot come in contact with the garment and causethe abrasion which is so objectionable in certain shields now upon themarket.

In some instances I may perforate the walls of the shield on theinclined sides, as shown in Fig. '7, instead of in the corrugations; butI prefer, where practicable, to perforate the shield only in thecorrugations.

Any means may be used to attach the shield A in position, and in Figs. &and. 5 I have shown a washer D, of adhesive plaster, which rests uponthe flange a and extends beyond it sufficiently to properly adhere tothe flesh.

In Figs. 1 to 5 I have shown the shield oblong in shape, while in Fig. 6I have shown a circular shield. Either one maybe used without departingfrom my invention.

When the garment is placed over the shield, as shown, for instance, bydotted line on, Fig. a, there will be an air-space all around the shieldwith which the space within the shield can freely communicate throughthe perforations 0, so that the wound is thoroughly ventilated, andthere is no liability of the openings being clogged by the garment. Furthermore, the portion of the shield upon which the garment rests isperfectly smooth, so as to prevent the abrasion of the garment andconsequent linting of the material.

I have shown the corrugations c tapered, being larger at the base thanat the crown, as this form is preferable, owing to the inclination ofthe side walls; but the corrugations may be of an even width throughout,if.dosired, and more or less inclination may be given to the side walls.

iVhile I prefer to make my shield of transparent celluloid, it may bemade of metal or other material without departin from my invention.

I claim as my invention- 1. As anew article of manufacture, a shield forprotecting scarified surfaces or other Wounds, said shield being shapedto form a crown, and having a base-flange, the side walls of the shieldbeing corrugated, with openings a crown and a base-flange, saidbase-flange i 5 7 extending entirely around the shield and inclined sidewalls, with corrugations in the side walls only and perforations withinthe corrugations, the edge of the crown being rounded so as to provide asmooth surface, 20

substantially as described. v

In testimony whereof I have signed my name to this specification in thepresenceof two subscribing witnesses.
